Abstract (en)

[origin: US2017201603A1] A user apparatus in a mobile communication system in which packets of a bearer are distributed among a plurality of base stations, and the distributed packets of the bearer are transmitted from the plurality of base stations to the user apparatus, including: a reception unit configured to sequentially receive packets of the bearer from the plurality of base stations; and a duplicated packet processing unit configured, when detecting an duplicated packet, from packets received by the reception unit, which is a duplicate of a packet, to determine whether re-establishment of a predetermined packet communication protocol including a header compression and decompression protocol is being performed in the user apparatus, and, when re-establishment of the predetermined packet communication protocol is not being performed, to discard the duplicated packet without performing header decompression processing of the duplicated packet.
